Be it known that I, CHARLES I. DA1 1GLnR,a-

citizen of the United States, residing at Cleveland, in the countyofOuyahoga and'stateof Ohio, have invented certain. new and usefulImprovements in Heating and Igniting At-- tachments forSteam-PropelledVehicles; and I do declare that the following is a full,clear,"

' and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

My invention has reference to a new and improved heating and ignitingattachment for steam-propelled vehicles; and the invention consists inthe construction and combination of parts substantially as shown anddescribed, and particularly pointed out in the claims. 1

In the accompanyingdrawings, Figure 1 is a sectional plan view of my newand improved attachment on" aline corresponding su bstantially to 1 1,Fig. 2; and'Fig. 2 is an outside elevation or face view ofthe'attachinent with the casing sectioned away-at the front to dis}close the internal parts.-- Fig. 3.-is a vertical sectional elevationof'the: attachment on line corresponding-to 3 3, Figs. lands, and showingan alcohol-lamp in position for -ini tial heating and lighting of theburner. I Fig.

Fig. 5is a plan section on a line corresponding to line 5 5, Figs. 3 and 4.Fig. 6 is a perspective elevation of the casing which incloses myattachment and constitutes an essential part thereof, as hereinafterfully described;

and Fig. 7 is a perspective elevation of the Serial No. 100,198. (Nomodel.)

erating condition, but to be in readiness for service and, in fact,performing a service at all times after being lighted and while thevehicleis kept under steam, as hereinafter fully described. 1 a

. Referring to the drawings, A, Fig. 6, represents the casing of theattachment and which'in'a'full-sized device does not necessarily exceedabout four inches in height, three in width, and two in depth,-front torear, and the said casing is preferably formed in two parts a and a,detach-ably but firmly connected together, so as to be the same inprantice as if the casing were made wholly in one piece. -The saidcasing is closed against air currents or drafts at all points, so thatit does not make any material difference inside how severe a wind may beblowing or at what speed vthe vehicle may be traveling. At its bottomthe casing is provided with a hinged "door A, in which there is an oilcup or reservoirja adapted to receive oil for initially heating andlighting in emergencies and when for any reason the alcohol-lamp B(shown in Fig. 3) is not available for such purpose. Usually andpreferably, however, the alcohol-lamp is used, because it can beturnedup to afiord a certain definite volfumeof'heat regardless ofbreezes or drafts,

and therefore serves as a safe and desirable medium for initial heating.this lamp is not available a sufficient quantity of oil may be droppedinto reservoir a and ignited for the purpose of starting the burner. Itwill be'noticed that the said reservoir has inclined edges deepestat thefront. Thisis for the purpose of allowingthe door "A to be droppedsufficiently to afford a sup =ply0f air for combustion, as seen in Fig.4,

which also prevents side draft,and hence does not interfere with theburning of the oil in said reservoir when this means of heating must beresorted to. A spring-catch a supports the bottom A, when saidbottom isin its lower or closed position, Fig, 4. When the alcohol lamp" B" isused, said bottom is dropped entirely down, as in Fig. 3,and when inclosed position the said bottom shuts off the draft from below,excepting such as may be provided for through small openings like aFigs. 3 and 7. The entire casing is thus closed against drafts oratmospheric dis- However, when turbances from the outside when all theparts are in working position, and its only material opening then is atits rear and top, Fig. 3, where there is free discharge into the spacebeneath the boiler B. Adrop cover or door a, Fig. 6, closes a smalllighting-opening in the casing through which a match can be in sertedfor ignition of the gas within.

The burner attachment D is inelosed within the casing A, exceptingcertain portions thereof extending out from the same for makingthenecessary valve and pipe connections. The said part D is preferably castin one piece throughout and is connected with the oil-supply pipe E,open to the source of oilsupply whatever and wherever it may be located,so that as the oil passes from said source it approaches the saidattachment D through the space beneath boiler B and the main burner F,and the said attachment is affixed to the end of said pipe by thecoupling parts (1, Fig. 1. It follows, of course, that all the oil orvapor consumed by the main burner F must pass through the attachment D;but as a matter of fact when the supply-pipe E becomes thoroughly heatedthe generation of vapor or gas is so complete therein that for the time-it does not depend upon the attachmentD to promote such generation, yetnotwithstanding the said attachment is kept lighted and in ageneratingcondition by its own resources, so that the main generator may be turnedoff at any time and as often as may be desired without depriving themain burner of a supply of vapor or gas for immediately starting thevehicle again after any stopgvhether short or long.

Now, having reference to the means for controlling the flow of oil orvapor through the part D, it will be seen that there are three differentvalves-G, H, and J, respectively-- and the construction and arrangementof said parts will be better understood when it is seen what thefunctions of these valves are.

Thus the valve G may be termed the initial or pilot light valvethat is,it controls the flow of oil to the initial heating cup or reservoir a ifit be used, and if not it controls the outflow of vapor that has beengenerated in the attachment by the heating thereof through alcohol-lampB. Thereafter and in the continued use of the valve G during a run ofthe vehicle the said valve is set to maintain flame and heat in theattachment sufiicient to keep it in a generating condition, so as to beable to start the vehicle at any moment, however long or short a time itmay have stopped. Theduet 2, leading from duct (P, Fig. 1, is constantlyopen to the supply-pipe E and is exclusively controlled by valve G.

Valve H is a hand-controlled valve from the seat of the driver andenables the driver to turn on more or less vapor to main burner F. In asense this is the main valve, as it is exclusively employed to determinethe quantity of vapor supplied to the main burner, and hence also thevolume of heat generated.

Said valve is, however, inward from or after valve J in respect tosupply-pipe E and in a measure subordinate thereto under certainconditions-that is, the valve J is an automatically-controlled valve byor through the usual steam -pressed diaphragm, (not shown,) bywhieh itscontrol is effected. If the steam be high, the said valve is supposed totell this fact by being more or less completely closed, and if the steambe low it is supposed to be wide open, the pressure of steam determiningits position automatically. The vapor having passed valve I-I, it issuesthrough duct 4 and nozzle 5 into mixer-tube L, Fig. 5.

All the valve-stems project out beyond casing A, as do also certainprojecting portions of burner attachment D, in which said stems orvalves are supported, and the needle form of valve is preferably used.To accommodate certain projecting portions of attachment D, casing A isprovided with swells 6 and 7, Fig. 6, and the said casing has ears 8,through which it is fixed in position.

Now, referring to the features of construction, it will be noticed thatpilot-valve Gdischarges into a mixing-tube 9, Figs. 3 and t, whence thegas issues beneath the spreader and deflector N, Figs. 1 and 3. This isaseparato part, preferably fixed to part D and extendinginward beneathboiler B and over the edge of burner F, through the rear opening incasing A and has fingers or projections 10 about its edge serving-asheat-distributers and to prevent the flame from going out by downdraft.

As to the direction of travel, the several valve-stems are at or towardthe front of the attachment, and the orifice through which the vaporissues into the main burner through mixing-tube L is at the rearthereof, where casing A serves as a perfect guard to keep off drafts andprevent blowing out when the vehicle is in motion.

The Vapor issuing from the pilot-orifice and mixer 9 impinges against aspreader 12, having down projections 13, adapted to break and distributethe vapor and flame.

The curved mixer-tube 9 is a separate part fastened by screws to theattachment-body D. A gauze or perforated metal sheet 14 serves as aninterior protection to the pilot-valve orifice discharging into tube 9.

In this device it will be seen that casing A has its inner side or wallslightly curved transversely to fit close up against the side of thecurved support B, and this cuts off all possible draft between saidparts and helps especially to protect the entrance of the vapors to mainmixer-tube L, Fig. 5. I might of course place a gauze hood over thisentrance;

valve J. This occurs by reason of duct 2, Fig. 1, being always in opencommunication with supply-pipe E outside of valve J.

Figs. 8 and 9 show the structural outlines of the attachment-body D, andthe peculiarities of construction,as shown,especially adapt said body tothe uses of my invention. These peculiarities comprise a solid top 16and a back 17 at right angles thereto, which .together sustain all theother portions of the body. It will be noticed that the channel 18 forthe steam-controlled automatic valve J lies directly across the frontand top of the body, with a right-angled projection 19 extending beyondthe top 16 relatively as shown and internally threaded to receive thesupplypipe connections 01. In addition to these features are theprojections 20 for the pilot-valve and projection 21 for the main valve,also extending outside of the main casing A, as clearly seen in otherfigures, whereby allor any of said valves or valve-stems can be removedwithout disturbing the said casing.

- It also becomes a matter of very great convenience to have theextension 22 for the main orifice-nipple 5 Wholly outside of the casingfor removal and cleansing the nipple at any time and by whicharrangement no other part of the attachment need be disturbed. run ofthe oil or vapor ducts in said body is clearly shown in the other views.

As herein shown, the bottom A of the casing is hinged on both sectionsthereof, and the entire top of the casing is a part of the frontsection, thus protecting against leakage into the casing.

By having the attachment-body D provided with a right-angled projection19 for connection with the oil or vaporsupply pipe I get the advantageof having the couplingor joint d for said parts outside of all otherparts and where convenient access is afforded for connecting anddisconnecting the attachment while all the other parts remain inoperative position.

The alcohol-lam p B may have a bail b suspended on a catch 7), Fig. 3,to temporarily support said lamp.

The functions of the so-called initialflame spreader 12 are veryimportant. Hitherto there has been trouble by reason of the initialflame often being allowed to run too high, so that itwould burn out thetop of the casing. Then, also, there was danger that currents wouldsteal through the attachment and blow out the flame. To overcome both ofthese objections, I have adopted the device seen in Fig. 10, which hasdownward projections 13 and wings serving as flame-breakers, thuspreventing concentration of the entire flame at any one point andinterrupting currents or drafts from blowing out the flame. By reason ofthe usual pressure sustained in the oil-supply the gas enters throughconduit 9 as from a blowpipe, and with a hotflame playd V- I T.)

The

ing about this device 12 it is indispensable to have some such device asthis for the purposes recited. The device N, Figs. 1 and 3,participatesin these functions and for this reason is substantiallyV-shaped in plan, thus guarding the inner space by its series ofprojections 10.

What I claim is 1. In initial heating and igniting apparatus, themain-burner casing, an attachmentcasing having a vertical inside wallbearing against said burner-casing and thereby cutting off allair-currents between them, in combination with a generator in saidattachmentcasin g having its vapor-su pply orifice for the main burneron the outside of said-attachment-casing andat the rear and in alinetherewith and in a position to be shielded by bottom thereon and adrip-cup on said bot-f tom the walls at the free end being of greaterheight than the walls at the hinged end, substantially as described.-

1. Theattachment-casing and the hinged bottom thereon and a drip-cup onthe said bottom the free end of which is deeper than the other end,substantially as described.

5. The attachment-body, the main burner at the side thereof, aflame-distributor on said body extending over and in close proximity tothe main burner comprising a-horizontal plate provided with dependingprojections aboutitsedgehavingtheirendsfree,'designed to hold anddistribute the flame over the burner, substantially as described.

6. The attachment-body having a pilotlight, a flame-distributer fixed tothe top-of said attachment-body in close proximity to the orifice ofsaid pilot-light and extending inward from said attachment-body, and'provided with a series of depending projections having their ends free andarranged at intervals about its edge, substantially as described.

7. The body-part attachment and'the initial-flame distributing andprojecting device fixed thereto and provided with a series of dependingprojections with their lower ends free and arranged in a tortuouslineacross the same, substantially as described.

Witness my hand to the foregoing specifi-'- cation this 10th day ofMarch, 1902.
